Title: Image data processing circuit
Inventor: MATSUI TOSHIHARU
IPC: H04N1/387
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To perform the magnification/reduction processing of image data without thinning true data to convert the resolution of the image data and to prevent the decline of image quality. SOLUTION: In this image processing circuit 20, the data are latched corresponding to a resolution conversion rate and interpolation data are added by a data interpolation circuit 23, and in an image reduction circuit 24, by thinning a serial transfer clock for latching the data, the interpolation data added by the data interpolation circuit 23 are thinned and the image data are reduced. Thus, resolution conversion is performed and the image data are reduced without thinning the true data. Also, by providing a white interpolation circuit 40 as the data interpolation circuit 23, since the data to be added at the time of data conversion are turned to white data, ink is thinned at the time of printing, a using ink amount is saved and the ink is quickly dried after printing in the image printing of many black parts.

IPC: G03G15/00
Filed: 1983-10-28
Abstract: PURPOSE:To simplify the constitution and to make carrying control of recording mediums easy by providing the third carrying means which guides and carries the recording medium, which is guided by a guide member and is sent with rotation in the reverse feeding direction of the second carrying means, to an image forming process on the way of the first carrying means. CONSTITUTION:Forward rotation of eject rollers 51 and 52 is stopped in the state where the carried rear end of a copy form Q is directed to a transfer path 18C by a projecting part of a guide plate 59, a prescribed time after passage of this carried rear end in the first detecting part 53. At this time, since the carried front end is on the outside of a device body 101A, the copy form Q is pulled out not to perform unnecessary copy on the rear face if the picture is judged visually to be bad. In this case, the second detecting part 54 detects whether the copy form Q exists or not for the stop time of eject rollers 51 and 52; and if the copy form Q is pulled out and its absence is detected before eject rollers 51 and 52 are reversed and driven, the second detecting part 54 outputs signal to a control discriminating part 250. The control discriminating part 250 releases a command, which reverses and drives eject rollers 51 and 62, to set them to the initial state.

Abstract: PURPOSE:To easily control an air/fuel ratio without labor in manufacture by outputting a dynamic brake signal to a dynamically braking circuit from a central controller when the rotating speed of a DC motor is fallen to reduce an air amount in a combustion chamber, and dynamically braking the motor by the braking circuit. CONSTITUTION:When present rotating speed of a DC motor 10 is reduced to a target speed to reduce an air flow rate, a central controller 16 inputs the present speed of the motor 10, and outputs an air flow rate regulation signal to a DC motor drive power source 22 corresponding to a difference between the target speed and the present speed. Simultaneously, a dynamic brake signal of a high level is output to the base of a transistor 28 of a dynamically braking circuit 24. Thus, the source 22 applies a DC voltage corresponding thereto to the motor 10 to reduce the speed of the motor 10 toward the target speed. On the other the opening of a gas flow control valve 6 is immediately controlled by the controller 16 to reduce gas amount, and an air/fuel ratio in a combustion chamber 4 is greatly controlled constantly at an excellent timing.

Filed: 1983-10-28
Abstract: PURPOSE:To reduce a duration time starting from an ignition to a time when a temperature in a combustion chamber is reached to such a value as enabling a vaporization combustion to be performed and provide an early resolving of red flame combustion by a method wherein restricting means is arranged not to perform a variable control until a signal in which a temperature in the combustion chamber is reached more than the desired value is received. CONSTITUTION:A temperature setting knob in an operation panel 42 is operated in response to a feeding volume of grain particles to be dried, and a reference value of hot air temperature is set by a hot air temperature setting circuit 44 in such a way as a temperature in a combustion chamber is reached more than a desired value in a short period of time and a vaporizing combustion in a burner 50 can be performed. A comparator circuit 46 outputs an H level signal if the temperature value in the combustion chamber is less than a hot air temperature reference value and the fuel control device 48 controls a flow rate of fuel to be supplied to the burner 50 to a uniform value. When the control device acknowledges that the value exceeds the reference value, L signal is produced at the fuel control device 48, a pulse signal of a duty ratio variable one is produced at the pulse driving circuit and then the control is transmitted to an on- time control for the flow rate of fuel.

Abstract: PURPOSE:To boost a voltage by using an existing external terminal by imparting a signal with an input level different from a range of a normal signal input level to the existing external terminal used for original signal processing operation, directly controlling an internal voltage drop and supplying an external power source voltage to a signal processing circuit. CONSTITUTION:When normal ECL circuit operation is performed by a voltage drop circuit part, 'H' and 'L' levels of a write enable signal -WEO are -0.9V, -1.7V respectively, and an SRAM becomes a read state when the signal -WEO is the 'H' level in the normal operation state, and becomes a write state When the 'L' level. At this time, a receiver circuit 1 operates as a differential amplifier, and an output signal S1 is inverted by an inverter 2 to be inputted to a switch circuit 3 as the signal S2 with the 'H' level. Thus, an nM0S transistor Mn1, a pMOS transistor Mp1 are turned on, and the nM0S Mn2 is turned off, and the output VE of the switch circuit 3 becomes the internal voltage drop level -3.3V in the normal operation of the SRAM.

Title: Electric washing machine
Inventor: OKAZAKI KIYOSHI
IPC: D06F39/00
Filed: 1991-08-12
Abstract: PURPOSE:To reduce wasteful power consumption by causing a display device to show the progress of a washing process or the like via an access detection means when a user is near a washing machine, while stopping the operation of the device when no user is near the washing machine. CONSTITUTION:When a user starts a washing machine after selecting a desired washing course, a display section 24 shows the progress state of a washing process. Upon the user's leaving the machine, no access detection signal is transmitted from an infrared sensor 19 and, therefore, the judgement is made that no person is present near the machine. Then, the operation of the display section 24 is stopped, for example, after waiting five seconds. This, however, is limited to the case where the output of an access signal does not continue, for example, one second or longer, not to stop the operation of the section 24 at the time of a person's momentary absence. When the user nears the machine, the sensor 19 judges that a person is present near the machine, thereby causing the display section 24 to operate. This is also limited to the case where the output of a signal continues, for example, one second or longer, not to cause the operation of the section, simply upon a person's passage near the machine. According to this construction, wasteful 7 power consumption can be reduced.
